View File Iron Bottom Sound Scenario This is a scenario to play the Iron Bottom Sound scenario from the Command at Sea Jumpstart. This is my first time working with SimPlot, so any input would be greatly appreciated. Submitter WarPigeon Submitted 01/03/2022 Category Scenarios  

View File Iron Bottom Sound Map This is a map for playing Battle of Savo Island or Iron Bottom Sound scenarios. I have not yet added depth zones, since I only intend to use it for surface scenarios, but I may do that in the future. I would appreciate any feedback, since it is my first stab at using SimPlot.

SimPlot 2.3 for Win10 View File Introduction SimPlot (short for Simple Plotter) is a utility program that supports Harpoon games by automating the movement process in a graphical environment. SimPlot uses a simplified X, Y coordinate system that makes range and bearing calculations easier. North is always at the top of the screen, and the 0, 0 coordinate is the center of the "game area". Each whole number of the coordinate system represents one nautical mile. Presently, SimPlot supports the display and movement for many of the common unit types found in Harpoon: surface ships, subs, aircraft, helicopters, missiles, and torpedo…

Finally got around to downloading 2.2.3, and am blown away by the changes made and the possibilities it opens up. These were just quick tests I did this morning with some maps for another project.

View File Bugout This is the SimPlot setup file for the Harpoon V scenario "Bugout" that is featured in The Naval SITREP issue #60 (April 2021). The installations are on the map, but the ships are not. This way, players may choose where to place them. All the naval ships and missiles that may be used in the scenario are importable, and are located in the Units folder. Civilian ships are an optional rule, but they are not included in the Units folder. They are very simple to create, with the only differences being the type and maximum speed (and size class, but that is not tracked in SimPlot). This scenario is compatible…

View File Guardian (Harpoon V Jumpstart Guide) Guardian is the scenario featured in the Harpoon V Jumpstart guide. The included map is a standard SimPlot version, unlike the Jumpstart version which was modified for printer-friendly colors. All the units (ships, helicopter, and missiles) that could be used in the scenario are pre-built and ready to be imported when needed. Submitter kmart494 Submitted 05/31/2021 Category Scenarios

I uploaded a new version of the User Guide. I finally filled in the missing procedures, and made corrections to obsolete information. This guide is compatible with the current version of SimPlot 2.0. It is still somewhat incomplete, but the section on creating and modifying units is complete. That is the area I get the most questions for, anyway. The file is available in the Downloads section.

Kevin - It is mentioned in SITREP60 that there may be a simplot2 file eventually for the Bugout scenario in the magazine. Does one already exist? I'm going to run this scenario soon and I can make my own easy enough but if the map image and txt file exist already for it (or for that matter, a full scenario file as well as the map files) Regards, Peter Robbins

I am so thankful that the Harpoon V world continues to make improvements, corrections, and enhancements to the rules and data books. Is there any errata available that would show what, specifically, the Jan 8th, 2021 changes were for each of the Harpoon V publications? That would make it a lot easier to fix platform sheets that may have an error on them, identify sections of the rules that perhaps I've been playing incorrectly, and digest new information or rules. Thanks a bunch in advance.

When searching for a sub using passive sonar I'm a little confused on how the initial detection works. I understand the tables, calculating the probability, etc.; however, when contact is made I'm not sure how accurate the initial location is. I've included a simple diagram of 2 squares (searching ships) that have made passive contact with a sub. The next step is for a helo or ASW plane to go find the sub based on the 2 ships' passive contact. I understand that the passive sonar contact won't tell me range or depth but does give direction. Is the passive sonar direction like the diagram on the left where each ship knows exactly what direction the sub i…

Are carriers powerhouses or sitting ducks? Can transatlantic convoys survive in a modern wartime environment? In the cat-and-mouse games between US and Russian submarines, which is better?

Hi all, In the interest of trying to build up the community a bit and get a sense for who else is out there that you might be able to play with I created a Google Form. https://forms.gle/G7xU2G2JesJrsMYo8 The link to the spreadsheet of responses is embedded in the receipt confirmation after submission.

Set up - An A-6E launches 2 Harpoon IC at a Kara class Soviet CG. The Harpoon will reach the Kara in 5 segments (2.5 minutes). The Kara detected it and rolled poorly on the Combat System Reaction table getting a total reaction time of 6 segments. So, the Harpoon will reach the Kara before the Kara can react with its Osa-M or Shtorm SAM systems. The Kara is broadside to the incoming Harpoons and, as such, has a 76mm gun and at least one 30mm CIWS that can shoot at the Harpoons. The Kara's MR-600 3D radar saw the Harpoons at launch, the MPZ-301 LAS radar for the Osa-M, the 4R60 Grom radar for the Shtorm, the MR-105 director for the 76mm, and the MR-123 director for…

In Harpoon scenarios that may span a few days or longer are there any tables or rules for aircraft readiness? For example - An A-6E flies off the carrier and returns in 4 hours, is readied in an hour, and flies off for another 4 hour patrol. How many times in a row can it do that before it needs a longer down time for maintenance, etc.? Another example - There is a squadron of 24 P-3Cs based in Iceland. How many of them would reasonably be expected to be mission ready (i.e. not down for maintenance, etc.)? Could all 24 get launched at once consistently or should xx% be expected to not be available at a given time? Perhaps this is too far into the …

I'm doing helo loadouts and I can't figure out how much various sonobuoys weigh. Any help is appreciated.

I have a SH-60B Block 0 Seahawk that lights its APS-124 SS radar from medium altitude attempting to find a Large surface contact. The radar LOS from the chart on pg 5-3 of the rules indicates that the maximum LOS is 175nm. The APS-124 maximum range for a large target is 160nm - so, 160nm is the maximum detection range. Section 5.2.5 of the rules for Airborne Surface Search Radars (SS) states that "these radars will pick up surface contacts and VLow air contacts at one-tenth of normal range". Question 1 - If I'm reading that correctly the detection range to a large ship will be 16nm (160nm max of the APS-124 SS divided by 10). Is that correct? Question 2 - If…

The following are procedures you can use to make background maps for Harpoon/Simplot scenarios. Presently, there are no "official standards" for SimPlot maps. I am still experimenting with various color combinations to make the gaming experience better. If a scenario does not require the presence of land features or specific starting points, ending points, or objectives, then a background map is not necessary. Procedures for using Internet maps: 1) Using your favorite Internet mapping website, select an area of interest for your scenario. If the area is not very large, then you may be able to get the entire area within the screen. 2) Using your fa…

https://discord.gg/t7pekGk in case anyone wants to join a fully public Harpoon 5 Multiplayer discord server. I can help you get to know Simplot2 and how to use it for double-blind games using the Discord channel. We have successfully used this method for both play by post (similar to PBEM style, submit orders, then update Simplot2 then show images then submit next turn orders) and real-time games. Discord offers both voice and video comms too for the realtime games or occasional "team" chats for Red or Blue teams. Excuse the double post to this general forum, but wanted folks to be able to find this if they want to take part. - Peter Robbins

I was looking into what air defence radar might be in operation in the UK and https://en.wikipedia.org/wiki/NATO_Integrated_Air_Defense_System#United_Kingdom suggests a combination of Lockheed-Martin AN/TPS-77 & AN/FPS-117 (which I understand are essentially the same, but the TPS-77 version is mobile) and a BaE Systems AR-327 in Cornwall. I wondered if my copy of H4.1 had stats for those radars so went to look. The annex notes on page 1 of "Data Annexes 4.1 - Ships, Aircraft & Weapons" suggests there should be a section J2 for "Land-Based radars" but my book seems to jump from "J1-6 - Annex J1 Naval Radars" straight to "K-1 - Annex K - Fire Control Radars".
